A chemist performs an experiment in which she varies the surface area of
10-g samples of zinc metal to determine how this will affect the reaction rate
of the zinc when it is mixed with 100 mL of hydrochloric acid. In this
experiment, which is the independent variable?
A. the mass of the zinc
B. the surface area of the zinc
C. the reaction rate of the zinc
D. the volume of the hydrochloric acid

After a big snowfall, you take your favorite rocket-powered sled out to a wide field. the field is 195 m across, and you know that your sled accelerates at a rate of 3.65 m/s2 when the rocket is on. how much time will it take the sled to cross the field starting from rest, assuming the rocket is on the whole time?

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
